Abstract (en)

Polyurethane-compact-foam material (I) with a carbon dioxide-charging degree of 0.03-0.20%, is claimed. An independent claim is included for the preparation of (I) comprising reaction injection molding of at least one polyol component (A) and an isocyanate (B) to give a mixture containing polyol component and the isocyanate (A+B) at the inlet of the injection molding or carbon dioxide foam mold.
